Tunneling of an electron from one composite fermion liquid into another in a bilayer system offers a unique spectroscopic probe into the short-distance high-energy physics of this highly nontrivial strongly correlated state. The authors identify the interlayer exciton responsible for the maximum current, and find excellent quantitative agreement with the experimentally measured energy as well as its dependence on an in-plane magnetic field. They also predict that the spin-polarization transitions of the fractional quantum Hall states as a function of the Zeeman energy will be marked by discontinuous jumps in the energy of this exciton.
